Hi, I have a question regarding a VNET with multiple address spaces and express route.
When creating a Azure Virtual Network gateway subnet with multiple address spaces, does it mater which address space i specify for the Gateway subnet?
I have a VNET with an existing address space and VMs and I am introducing express route which dictates my address space in my scenario. Rather that restore the VMs to a different VNET I would like to add an additional address space and then change the IPs of the vms to the expressroute address space.
There is an existing site to site VPN inplace using the original address space (gateway subnet) that I need to leave inplace.
Can I setup my new expressroute with the new address space but still use the existing gateway subnet belonging to the original address space? Will express route care about the gateway subnet being on a different address space to what it is routing to?
